This study analyzed the effect of organizational culture and leadership of technology SMEs on psychological capital and organizational effectiveness. For the data collection of this study, 479 effective questionnaires were used as statistical analysis data using Google questionnaires for those engaged in technology SMEs in Busan, Ulsan, and Gyeongsangnam-do from August 9 to September 8, 2021. The analysis results are as follows. First, the hypothesis that the organizational culture and leadership of technology SMEs will affect psychological capital was analyzed. As a result, it was found that group culture, development culture, rational culture, and conditional compensation had a positive (+) effect on self-efficacy. In addition, group culture, rational culture, and conditional compensation also had a positive (+) effect on resilience. Second, as a result of analyzing the hypothesis that psychological capital will affect organizational effectiveness, we found empirical evidence that self-efficacy and resilience had a positive (+) effect on innovative behavior, and resilience had a negative (-) effect on turnover intention.

In this paper the micro mouse system with high stability is proposed. Hardware system of micro mouse is configured by PCB layout and artwork after simplifying the circuits using EPLD(Erasable Programmable Logic Device). Also, advanced motion algorithm using new motion table is introduced. As a result of manufacturing micro mouse and carrying out motion experiment, it is confirmed that the reduction of motion period in micro mouse is depend on not maximum speed but acceleration and deceleration method. Therefore, it is shown that configuration and application of proposed motion table in micro mouse system can improve conventional motion algorithm.

본 논문에서는 통신 기지국용 전원으로 사용할 수 있는 주파수 제어 직렬 공진형 컨버터의 동작 원리 및 특성을 살펴보고 실제의 전원 시스템을 설계 및 제작하려고 한다. 주파수 제어 공진형 컨버터 시스템은 POSR(Parallel Output Series Resonant) 형태이기 때문에 부하에 강인하고 주파수를 제어함으로써 입력전압의 변화에도 안정된 출력을 보여준다. 실제 시스템 제작에 앞서 먼저 시뮬레이션을 통한 시스템의 분석을 하였고 시뮬레이션 프로그램은 ACSL(Advanced Continuous Simulation Language)을 사용하였다.

In this paper new control strategy of series resonant converter system for control power supply is suggested. Frequency controlled series resonant converter system is robust to load variations because it is POSR(parallel output series resonant) type. And it provides stable output voltage by changing switching frequency to input voltage variations. Firstly, operation analysis about suggested series resonant converter system was carried. Then simulations using ACSL(Advanced Continuous Simulation Language) and experiments to actual system were carried to prove characteristics of suggested system.

본 논문에서는 통신 기지국용 전원로사용할 수 있는 직렬 공진형 컨버터 시스템의 새로운 제어방식을 제안하였다. 주파수 제어 직렬 공진형 컨버터 시스템은 병렬 출력 직렬 공진(Parallel Output Series Resonant : POSR)형태이기 때문에 부하변동에 강인하다. 또한 스위칭 주파수를 제어함으로써 입력전압의 변화에도 안정된 출력을 제공한다. 실제 시스템 제작에 앞서 제안된 병렬 출력 직렬 공진형 컨버터 시스템의 분석을 하였고 ACSL(Advanced Continuous Simulation Language)을 이용한 모의실험을 하였다. 또한 실제의 시스템을 제작 및 실험을 통하여 시스템 특성을 확인하였다. In this paper new control strategy of series resonant converter system for power supply of communication station is suggested. Frequency controlled series resonant converter system is robust to load variations because it is POSR(Parallel Output Series Resonant : POSR) type. And it provides stable output voltage by changing switching frequency to input voltage variations. Firstly, operation analysis about suggested series resonant converter system was carried. Then simulations using ACSL(Advanced Continuous Simulation Langage) and experiments to actual system were carried to prove characteristics of suggested system.
